Thoreau calls and reports about the reading of his lecture on Brown at Boston and Worcester. Thoreau has good right to speak fully his mind concerning Brown, and has been the first to speak and celebrate the hero's courage and magnanimity. It is these which ho discerns and praises. The men have much in common, — the sturdy manliness, straightforwardness, and independence. It is well they met, and that Thoreau saw what he sets forth as none else can. Both are sons of Anak and dwellers in Nature, — Brown taking more to the human side, and driving straight at institutions, while Thoreau contents himself with railing at and letting them otherwise alone. He is the proper panegyrist of the virtues he owns himself so largely, and so comprehends in another.
